Design And Implementation Of An Integrated Navigation System In Outdoor And Indoor Environment

An Effective navigation service can bring a lot of convenience for people's life. It will help users to save time to find the destination. Besides the demands of navigation service in outdoor environment, people also have a strong demand for indoor navigation service. With the development of the mobile phone, navigation service on mobile device is widely used. While current research on navigation service is mostly based on the outdoor environment and indoor environment separately. And there is not an approach to integrate outdoor and indoor navigation service together. This thesis aims to provide a method to integrate the outdoor and indoor navigation service together on user's intelligent mobile device, which will improve user's navigation experience.The integrated navigation system includes two subsystems, the map service subsystem and the route searching subsystem. The thesis firstly introduces some key technologies used in the system, such as the web2.0 concept, Google map model and MVC design pattern. Then the thesis describes the system's overall function and the demand analysis of the two subsystems. Based on the analysis, the thesis provides the system design schema and discusses in detail about the implementation and design of the map service subsystem and the route searching subsystem.The thesis mainly discusses about the implementation and design of two subsystems. The map service subsystem includes map presentation module, map tile obtaining module, the map type definition module and the map control button definition module. In the route searching subsystem, the thesis designs the subsystem framework, the data format between client and server, database structure and the class definition. Finally, through analyzing the result of the system test, the functions of the system is validated, and it is proven that the function and performance of the system meet the design requirements.In the end, the summary of the whole thesis, current shortcomings of the system and future work are given. Also, the summary of my work and research progress during master-degree study are described.
